Description

Technical Field

[0001] This utility model belongs to the field of packed tower technology, and in particular relates to a packing support structure for packed towers. Background Technology

[0002] Packed towers are common gas-liquid mass transfer devices widely used in chemical, petroleum, and environmental protection fields. They are filled with packing material to increase the gas-liquid contact area and improve mass transfer efficiency. The packing support structure is a crucial component of a packed tower, its main function being to support the packing, ensuring its stability and uniform distribution within the tower while allowing gas and liquid to pass smoothly. While the design and application of packing support structures are quite mature, some issues still exist that affect their performance and reliability. For example, in existing grid support structures, thin grid plates can lead to insufficient strength and rigidity, causing the support structure to deform easily and resulting in uneven packing distribution, thus affecting mass transfer efficiency. Increasing the grid plate thickness can solve the structural strength problem, but it significantly hinders gas and liquid flow, affecting the uniformity of gas and liquid dispersion and negatively impacting mass transfer efficiency. Utility Model Content

[0003] In view of this, the present invention aims to propose a packing support structure for packed towers to solve the problem that the existing grid support structure is not conducive to the uniform dispersion of gas and liquid, thus affecting the mass transfer efficiency.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows: A packing support structure for a packed tower includes a support ring with multiple support members spaced apart, and ventilation gaps between adjacent support members. Each support member includes an upper support portion and a lower support portion. The upper support portion has a liquid collection trough in the middle, with the length direction of the liquid collection trough being the same as the length direction of the support member. The upper support portion has through holes at positions corresponding to the bottom surface and side wall of the liquid collection trough. The lower support portion includes support plates, with two support plates at the connection points between the bottom surface and side wall of the liquid collection trough. There is a liquid drop gap between the two support plates, and the liquid drop gap communicates with the through holes on the bottom surface of the liquid collection trough.

[0005] Furthermore, the support plates are inclined, and the two support plates are arranged in a figure-eight shape.

[0006] Furthermore, the upper support is provided with guide edges on the left and right sides, and there is a guide gap between each guide edge and the support plate. The guide gap is connected to the through hole on the side wall of the liquid collection tank.

[0007] Furthermore, one end of the guide edge is fixed to the support, and the other end is set obliquely downward or horizontally.

[0008] Furthermore, one end of the guide edge is fixed to the support member, and the other end is provided with a curled portion.

[0009] Furthermore, multiple through holes are spaced apart along the length of the liquid collection tank.

[0010] Furthermore, the through hole includes a side through hole provided on the side wall of the liquid collection tank and a bottom through hole provided on the bottom surface of the liquid collection tank. The side through hole is a strip-shaped hole, with one end of the side through hole facing the bottom through hole and the other end facing the guide edge.

[0011] Furthermore, the upper support portion has a recessed portion corresponding to the position of the bottom through hole.

[0012] Furthermore, the upper support portion is provided with serrated protrusions around the bottom through hole.

[0013] Compared with the prior art, the packing support structure for packed towers described in this utility model has the following advantages: The packing support structure for a packed tower described in this utility model has the advantages of high structural strength, providing stable support for the packing and being less prone to deformation. By spaced-apart support members on the support ring, the structural strength and rigidity of the support ring are improved, while simultaneously meeting the requirements for gas and liquid passage. Furthermore, by providing through holes on the upper support portion of the support member and a support plate on the lower support portion to separate the through holes on the bottom and sidewalls of the liquid collection tank, gas and liquid can be dispersed, allowing gas to flow into the packing more evenly and liquid to seep down evenly through the through holes, thus improving mass transfer effect and efficiency.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] A packing support structure for a packed tower, such as Figures 1 to 4As shown, the device includes a support ring 1, on which multiple support members 2 are spaced apart, with a ventilation gap 4 between adjacent support members 2; each support member 2 includes an upper support part and a lower support part, with a liquid collection tank 7 in the middle of the upper support part, the length direction of the liquid collection tank 7 being the same as the length direction of the support member 2, and through holes 3 at positions corresponding to the bottom surface and side wall of the liquid collection tank 7 on the upper support part; the lower support part includes support plates 5, with two support plates 5 at the connection between the bottom surface and side wall of the liquid collection tank 7, and a liquid drop gap between the two support plates 5, the liquid drop gap communicating with the through holes 3 on the bottom surface of the liquid collection tank 7.

[0021] Specifically, by arranging multiple support members 2 with the above-mentioned structure at intervals, the structural strength and rigidity of the support ring 1 can be improved, while meeting the requirements for the passage of gas and liquid. In addition, by providing through holes 3 on the upper support part of the support member 2 and providing support plates 5 on the lower support part to separate the through holes 3 on the bottom surface and side walls of the liquid collection tank 7, the gas and liquid can be dispersed, allowing the gas to flow into the packing more uniformly and the liquid to seep down uniformly through the through holes 3, which is beneficial to improving the mass transfer effect and mass transfer efficiency.

[0022] Preferably, the support plates 5 are inclined, and the two support plates 5 are arranged in a figure-eight shape. For example, the support plates 5 are fixed to the support member 2, which can be fixed to the support ring 1 by conventional methods such as welding. By adopting the support member 2 with the above structure, the support member 2 can form an X-shaped inner support on the support ring 1. Compared with support members 2 with other structures, this structure of support member 2 has higher structural strength, takes into account both lightweight and strength, and is conducive to improving the overall structural strength and rigidity of the support ring 1, reducing the probability of deformation of the support ring 1, and ensuring that the filling remains uniform.

[0023] Preferably, the upper support is provided with guide edges 6 on the left and right sides respectively, and there is a guide gap between each guide edge 6 and the support plate 5. The guide gap is connected to the through hole 3 on the side wall of the liquid collection tank 7.

[0024] For example, the guide edge 6 is fixed to the support member 2. The guide edge 6 not only improves the structural strength and support area above the support member 2, but also strengthens the local strength of the support member 2 while meeting the requirements of lightweight design, so as to ensure that the support member 2 can provide stable support for the packing. Moreover, the guide edge 6 can also guide and divert the gas rising through the ventilation gap 4. After the gas is blocked by the guide edge 6, some of the gas can continue to flow upward through the through hole 3 on the side wall of the liquid collection tank 7, while the remaining gas can continue to flow upward through the ventilation gap 4, thereby achieving uniform dispersion of the gas and improving the gas treatment effect of the packing.

[0025] In an optional embodiment, one end of the guide edge 6 is fixed to the support member 2, and the other end is set obliquely downward or horizontally. Compared with other structures, the obliquely downward-set guide edge 6 has a better guiding and dispersing effect on the gas, which is beneficial to improving the uniformity of the gas after passing through the support structure. The horizontally set guide edge 6 can increase the support area of ​​the support member 2 on the packing, while still satisfying the guiding and dispersing function of the gas, and has better applicability. Those skilled in the art can choose a suitable guide edge 6 structure according to actual needs, which will not be elaborated here.

[0026] In another optional embodiment, one end of the guide edge 6 is fixed to the support member 2, and the other end is provided with a curled portion 12. Compared with other structures, the curled portion 12 structure has higher structural strength, which can better enhance the structural strength above the support member 2, while also satisfying the function of guiding and dispersing gas. Those skilled in the art can select a suitable guide edge 6 structure according to actual needs, which will not be elaborated here.

[0027] Preferably, multiple through holes 3 are spaced apart along the length of the liquid collection tank 7. For example, through holes 3 are provided on the bottom surface and left and right side walls of the liquid collection tank 7, and multiple through holes 3 are spaced apart along the length of the liquid collection tank 7. By spaced out multiple through holes 3, not only can the gas passage efficiency be improved, but it is also beneficial to further disperse the gas.

[0028] In practical applications, the through-hole 3 includes a side through-hole 10 on the side wall of the liquid collection tank 7 and a bottom through-hole 11 on the bottom surface of the liquid collection tank 7. The side through-hole 10 is a strip-shaped hole, with one end facing the bottom through-hole 11 and the other end facing the guide edge 6. Specifically, the side through-hole 10 is a strip-shaped hole, with the lower part for liquid passage and the upper part for gas passage. When liquid in the packing seeps down, most of the liquid flows into the liquid collection tank 7 and is dispersed through the through-holes on the bottom and side walls of the liquid collection tank 7 before continuing to fall. The liquid flowing out through the through-holes on the side walls of the liquid collection tank 7 can flow along the surface of the support plate 5 and finally fall away from the through-holes on the bottom surface of the liquid collection tank 7, thus achieving uniform dispersion of the liquid.

[0029] Preferably, the upper support portion has a recessed portion 8 at the position corresponding to the bottom through hole 11, and the upper support portion has serrated protrusions 9 around the bottom through hole 11. By providing the recessed portion 8 and the serrated protrusions 9, a secondary liquid separation structure can be formed at the position of the bottom through hole 11, preventing the liquid from falling directly through the bottom through hole 11. Secondly, secondary dispersion can be achieved under the guidance of the recessed portion 8 and the serrated protrusions 9, which is beneficial to further improve the uniformity of liquid dispersion.

[0030] The packing support structure for a packed tower described in this utility model has the advantages of high structural strength, providing stable support for the packing and being less prone to deformation. By spaced-apart support members on the support ring, the structural strength and rigidity of the support ring are improved, while simultaneously meeting the requirements for gas and liquid passage. Furthermore, by providing through holes on the upper support portion of the support member and a support plate on the lower support portion to separate the through holes on the bottom and sidewalls of the liquid collection tank, gas and liquid can be dispersed, allowing gas to flow into the packing more evenly and liquid to seep down evenly through the through holes, thus improving mass transfer effect and efficiency.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
